\item \textit{Notes}. The outcome variable is an indicator that equals 1 if household \(i\) in hamlet \(j\) purchased at least one of the two ICS promoted during the intervention. Columns (1) and (2) present the mean and standard deviations, respectively, for the MCMC sample. Column (3) presents the 95 percent credible interval for the MCMC sample. Estimates for the district fixed-effect and the 97 hamlet-specific random effects not reported for brevity. As in Table \ref{t:purchase_rates}, \(N = 943\) households.}
